Our Practice

We advise our clients on a wide range of matters, from sorting out the kinetic and mechanistic details of chemical reactions, to optimizing disinfection regimes for public drinking water utilities, to designing defensible water safety management programs for healthcare facilities.

Waterborne Disease Outbreak Response (Buildings)

Most waterborne disease outbreaks in the US are plumbing associated. We help clients respond quickly and decisively to outbreaks of waterborne infections, such as those caused by Non-Tuberculous Mycobacteria (NTM), Pseudomonas, and Legionella (Legionnaires' disease).  Often, we represent clients in discussions with departments of health to develop and implement site-specific remediation plans. 

Water Safety Management (Buildings)

 We help clients develop, implement and document comprehensive, sustainable  programs to prevent plumbing-associated waterborne illnesses.  We design disinfection protocols, paying close attention to the measurement and management of disinfectants and disinfection byproducts. Our comprehensive approach allows us to meet multiple objectives-- e.g.,  efficacy, safety, corrosion control and compliance with regulations.  Our water safety management programs are based on Hazard Analysis and Critical Control Point (HACCP) methodology, consistent with the recommendations of the US Centers for Disease Control (CDC),  World Health Organization (WHO) and others.


We help clients understand and comply with laws, rules, regulations, codes and industry-consensus standards that apply to the transport, handling and application of chemical disinfectants. Our work includes programs for compliance with the Federal Safe Drinking Water Act (SDWA) and corresponding State regulations, including those governing continuous supplemental disinfection (CSD) of domestic hot and cold water in buildings. Our water safety management programs meet the requirements of ASHRAE Standard 188, Legionellosis: Risk Management for Building Water Systems.  


We advise our clients on matters related to the environmental chemistry, transport and fate of chlorine-related chemicals. This work includes the development of applications for government permits as well as litigation support and expert testimony in complex Superfund cases.

Chemistry (Products & Processes)

We help clients to measure, characterize and understand in detail the observed (sometimes unexpected) chemical reactions that can affect products and processes. Often, we are able to determine boundary conditions, important to avoiding potentially catastrophic events associated with unanticipated upset conditions. This work often is associated with the development of new products and processes as well as with patent litigation.
